Abstract: Objective To observe the clinical curative effect of bipolar radiofrequency combined with L-vitamin C in thetreatment of facial photoaging patients. Methods A total of 37 patients of facial skin photoaging were selected from May 2016to April 2018. The patients were treated with bipolar radiofrequency (once every 4 weeks, 3 times), and the L-vitamin C wasused immediately after each treatment. CK skin test instrument and VISIA skin detector were used to test the facial indicatorsin pretherapy and post-treatment. CK skin test instrument was used to detect skin elasticity, sebum content, melanin, heme,skin moisture content and trans epidermal water loss. VISIA was used to analyze the characteristics of color spots, wrinkles,pores, textures, uv spots, red areas, brown spots and porphyrins before and after treatment. Results The skin elasticity increasedafter the treatment testing by CK skin detection instrument, and the difference was significant( P ＜0.05). Sebum content,hemoglobin, and melanin index decreased after treatment, and the difference was significant( P ＜0.05), but the change in Transepidermal water loss and moisture content were not obvious. The improvement of spots, pores, textures, brown spots, uv spots,red areas and brown spots after treatment detecting by VISIA skin testing instrument was significant( P ＜0.05). However, theimprovement of wrinkle and purple indexes were not obvious. Conclusion The treatment of Bipolar radiofrequency combinedwith L-vitamin C can effectively improve the skin condition of patients. This method can be used as one of the treatment offacial skin photoaging.
